Methods and systems for creating and rendering skins are described. The optical component includes a photosensitive glass andor a photosensitive glass ceramic and a plurality of structures influencing propagation of light in at least a part of the photosensitive glass andor a photosensitive glass ceramic. The present invention enables the use of fully differential strobe signals to improve electrical performance of the source synchronous data transfers while removing the noise sensitivity problem associated with these signals. The system utilizes an advanced graphical user interface, which allows users to access and manage systems using a simple point and click methodology. The flexible element is secured by the locking assembly such that the flexible element is fed from the second member as the second member is moved away from the first member until the flexible element is anchored within the second element and the second element is correspondingly restrained from moving further away from the first member.
